Some Rulings which are Time-Bound

I asked him about the sick person – how does he prostrate? He said: on a small palm-leaf mat or on a hand-held fan or on a tooth-stick which is raised to him [made to touch his forehead], and it is better than gesturing [without the forehead touching anything], verily the one who dislikes prostrating on the hand-held fan dislikes it because of the idols which used to be worshiped apart from Allah, and we never worship anything besides Allah ever – so prostrate on the fan and on the tooth-stick and on a piece of wood.

among that which reached me from the Shaykh Abi Ja`far Muhammad b. Uthman قدس الله روحه as answers to my questions to the Master of the Age عليه السلام … as for that which you have asked about in regards the one who prays while the fire, or an image, or a lamp is in front of him – is his prayer accepted? [you ask this] because the people in your midst have differed about that – then – it is permissible for the one who is not a direct descendant of the idol-worshipers or fire-worshipers to pray while the fire, or an image, or a lamp is in front of him, and it is not permissible for the one who is a direct descendant of the idol and fire worshipers.

the prophet صلى الله عليه وآله had prohibited that the meat of the sacrificed animals (in the Id festival) be kept for more than three days because of the prevailing need, as for today then there is no harm in doing so.
